To @ZZ whom, it may concern:

Be it known that I, EZRA COPE, ol" Hamilton, Butler county, Ohio, have invented certain new and useful Improvements in Solar- Printing Apparatus, of which the following is a speciiication.

This invention pertains to solar-printing apparatus, and it relates to the arrangement of part-s i'or j ierjnitting a ready adj ustment of the exposurepiece-such as a printing-frameM into a proper correspondence with the direction of the suns rays.

The invention will be readily understood i'rom the following description, taken in connection with the accompanying drawings, in which- Figure l is a side elevation of a printing apparatus illustrating my invention, and Fig. 2 a vertical section of the same.

I illustrate my invention as embodied in an apparatus mounted upon a crane, so as to be readily projected outward from a window, as is common in large j )rinting-frames.

In the drawings, A represents a crane-post, such as is usually secured to the iioor or wail justwithin the window at which the apparatus is used; B, a j ilo swiveling upon the crane-post; C, an arin, forming an extension of the jib; D, a pivot-joint, with a vertical axis, uniting the arm O to the jib, whereby an articulated system is produced, as usual; E, a printing i'ranie of ordinary construction, adapted to receive sensitive paper, a negative, d'0.; F, a pivot-bearing with a horizontal axis at the joint I), in which is journaled theinner end ofthe arin C; G, a worm-gear fast upon the extreme inner end of the arm C 5 II, a worm and hand-crank by which the worm-gear and the arm G are revolved upon their axis; I, a slide iitted to reciprocate within the arm G, which is hollow; J, a mortise through the side of the arm C under the printing-frame; K, a cranked screw journaied in the arm and engaging the slide I in such manner that by turning the screw the position of the slide in the arm may be longitudinally adjusted, as will be obvious from Fig. 2 of the drawings; L, supportinglugs projecting from the side of the arm at its end where the mortise J is located andin position to receive the connections of the printing-frame; M, a lever attached to the printing-frame, fulcrumed upon an axis at right angles to the axis of rotation of the arm supported by the lugs L, and engaging with its lower end the mortise in the slide I; N, aturntable plate formed upon the upper end of the lever M; and O, a bearing-clamp, by which the printing-frame is att-ached to the turn-table, so as to secure the printing-frame to the lever, and at the same time permit the printingframe to be revolved upon an axis at right angies to its own plane.

The printing-frame is supported horizontally within the room for preliminary manipulations, and is projected out of the window for exposure, in a manner common to printingiframes mounted upon cranes. After the frame has been projected out or the window, the angle of exposure must be adjusted to suit the inciination'of the solar rays.

My invention has to do exclusively with these movements of adjustment for exposureangle. By means of the worm and worm-gear the arm may be revolved and the printingframe thereby adjusted in a circle whose axis -coincides with the axis of the arm-bearing.

By adjusting the slide I inward or outward the lever M is osciliated, and the printingframe may thereby be adj ustedin an arc whose axis is the fulcrum-pivot of the lever and which is at right angles to the axis of rotation of the arm-hearing. By means of these two motions any desired angle of exposure in any direction may be obtained. The turn-table motion is as usual, and is for convenience in the preliminary manipulations of the printing-frame. It should be understood that either one ofthe two motions provided maybe usedin the adjustment of the printing frame through the diurnal arc. Thus the arm may be' rotated into an adjustment suited to the latitude, and then the slide and lever may be used for the diurnal adjustment; or the lever and slide may be used in the preliminary adjustingvof the printing-'frame into correspondence with the latitude, and then the arm may be rotated for the diurnal adj ustment. The appropriation of these movements relatively will ofcourse dependlargely upon the direction of the approach of the solar rays with reference IOO embodiment ol" the principle oll in v invention in apparatus other than solar-printing apparatus-Snell. llor instance, as solar ea-nleras, telescopes, tte. l therefore herein deiine, a"
